The Avengers may be a team of stellar superheros, but Metro Vancouver now has “The Unflushables” – a duo that goes by the name Pee and Poo.

Their mission: Send a memorable reminder to watch what you flush down the toilet and keep it to the absolute basics.

Despite packaging that suggests they are flushable, wipes are the most commonly disposed item that needs to stay out of the sewage system, according to Metro Vancouver.

Dental floss, hair, tampons and applicators, condoms, medications and paper towel also cause clogs, which can cost millions of dollars a year to deal with, according to regional board chair and Coquitlam Mayor Richard Stewart.

“That includes the chemicals that get flushed but it includes having to open up pumps and try to unclog them, repair damage to the infrastructure that moves our flushed products through our system to a sewage treatment plant – and that’s a real cost to taxpayers,” he said in a video posted on social media this week.
